What to do?

[khuck2002]

So I have a 90 gallon tank and I am pretty new to the hobby, the tank currently has a niger trigger a picasso trigger a figure 8 puffer a damsel and a lion fish in it my question is what can I do about all of the algae that is accumulating on the rocks right now it is mostly green algae. thanks

you will need to feed more carefully, no wasted food and maybe feed less. do more water changes, pull out as much algae as you can and it will eventually go away. you need to make sure you are taking out as much nutrient as you are putting in with the food. are you using a skimmer or ro/di filter for your freshwater? these will help a lot
